I picked up this "MC AUTO CPC PHASE 2 CCT" 28mm "MACRO" ƒ2.8 lens for $5 at a local camera store and played with it for a bit over a week, which happened to coincide with a vacation to Baltimore & DC.
(Ignore the aperture info in the metadata, I stuck a piece of foil over the "A" pin so my camera thinks every lens is at minimum an A now. Pretty much everything is either F2.8, F8, or F11)
Closeup of some leaves. I forget if I was testing the "macro" focus or just wanting to see what the bokeh looked like

The Sip & Bite (sometimes called the sit & fight), I think the oldest diner in Baltimore. (got a speck on the sensor of the camera which is really obvious here, but I didn't notice it for a couple of days
)
The USS Torsk Submarine (part of the baltimore inner harbor's floating museum)
Crew's Quarters on the USS Constellation (part of the baltimore inner harbor's floating museum)
I forget the name of the statue, but it's a monument to Polish soldiers killed by Germans and Russians in the second World War
These are straight off the camera. There are more, and the post-production versions, here:
